Barksdale L1X-H204S Temperature Switch
Rp123000.00
Manufacturer / Brand: Barksdale
Type: Explosion-proof mechanical temperature switch (local mount, single setpoint)
Description
The Barksdale L1X-H204S is an explosion-proof mechanical temperature switch in the L1X series, intended for use in hazardous environments (Class I, Division 1 & 2). It provides a single setpoint SPDT (Single Pole Double Throw) switching action when a configured temperature threshold is reached. The “H204” range means it is adjustable over a span from –50 °F to +200 °F (–45 °C to +93 °C). The “S” denotes that wetted parts are stainless steel (304 SS) rather than copper. The unit incorporates a tamper-proof external adjustment knob, enclosed terminal strip, and rugged construction suitable for industrial and process control applications.
It is designed for direct mounting (local immersion) of the temperature sensor (no capillary), making it ideal for applications such as monitoring equipment temperature, safety alarms, or auxiliary control where robust and reliable switching is required in hazardous areas.
